manual

i'm looking to get a copy of our manual. On the top of our unit is coils (kind of like a radiator (they are all in a row and look like upside down u's) and there is water line to the radiator. That is what makes me think it is a humidifier on it. Unfortunately we were not left with any manuals and i've been pretty lucky in finding the stuff online except for this. They have a emerson air cleaner attached to the side of the unit but it is the water going into the furnance that has us stumped.

The coil you are talking about is the other half of your air conditioner system. Your furnace is a condensing furnace, meaning your combustion exhaust cools to the point of condensation. The condensate has to be drained away from the furnace. Often on a furnace of that age, the leaking is caused by a cracked heat exchanger. You'll want to call a service professional and rule out a cracked heat exchanger, which could be a potentially dangerous situation.
